Such problems as large fluctuation of pressure in condensate header
mismatch of the pipe capacity for condensate recycling and the condensate water flow variation occurred during the operation of condensate system in 4×600 MW sub-critical air-cooled unit for Shaanxi Guohua Jinjie Energy Co.
Ltd.Thus
countermeasures like frequency conversion transformation were carried out.After the improvement
the pipe vibration was eliminated
and the electric consumption in condensate system was decreased.When the unit load was below 450 MW
the power consumption index of the condensate pump was lower than 50%.
